I am having this same issue. Did you figure it out @kk17?

No，I use another plugin instead.

@architek1 what about you? could you make it work?

Like what's really bad it looked very promising

from ble-framework.

If Any one is facing problem for finding nearby bLE devices replace line in BLE.mm inside function : findBLEPeripherals

[self.CM scanForPeripheralsWithServices:[NSArray arrayWithObject:[CBUUID UUIDWithString:@RBL_SERVICE_UUID]] options:nil];

with

NSDictionary* scanOptions = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES], CBCentralManagerScanOptionAllowDuplicatesKey, nil];
[self.CM scanForPeripheralsWithServices:nil options:scanOptions];

@emdepdev if you fixed the problem can you please submit a pull request?

I think I know what is your problem. Are you sure that the RBL_SERVICE_UUID defined in BLEDefines.h is the same of your board? Please verify that you have one of these boards.

• BLE Shield
• BLE Mini
• Blend Micro
• Blend
• BLE Nano
• RBL nRF51822

I have BLE Mini and I tested the code on master in iOS 9 and iOS 11 and it works.
The code you want to change would cause the framework to find multiple devices different from the specific RedBearLab boards for which the framework was created (including duplicate UUIDs). Apple documentation clearly states that you should avoid this behavior to improve battery efficiency.
Read paragraphs Minimize Processing of Duplicate Device Discoveries and paragraph Only Discover Services and Characteristics You Need in the documentation https://developer.apple.com/library/content/documentation/Performance/Conceptual/EnergyGuide-iOS/BluetoothBestPractices.html.

If you want to support another board different from RedBearLab boards I suggest to change the values defined in the BLEDefines.h with those of your board and then try to adapt the code. I can not guarantee that this will work because this framework is intended for the specific boards in the list above.

I am closing the issue.
